CATDOLL : CATDOLL: How many snakehead fish can be raised in one acre?

A maximum of 10,000 fish fry can be released.

The breeding density of snakehead is relatively high, with a pure water surface area of ​​660 square meters per mu. 10,000 snakehead fry can be placed in the fish pond. Snakehead grows fast, with small ones weighing 1.1 kg and large ones weighing up to 3 kg. Snakeheads have strong vitality and will be laid flat in the fish pond when they are released. The feed for snakeheads is granular defatted fish meal, so a high breeding density will not pollute the water source and affect the growth of snakeheads.

.Fish stocking generally comes from two sources: wild and artificially bred. Regardless of the source, fish species must be screened before being put into the pond. Fish species with basically the same specifications should be bathed in 3% to 5% salt water for 5 to 10 minutes and then put into the same fish pond. The stocking density depends on the water source, drainage conditions, and the source of bait fish. Generally, 6,000 to 10,000 fish species of 3 to 5 cm in length are stocked in 667 square meters; 4,000 to 6,000 fish species of 10 to 15 cm in length are stocked; and about 2,000 fish species of about 20 cm are stocked. If the water source and drainage conditions are good and the source of bait fish is sufficient, the stocking density can be appropriately increased.

2000 to 2500 silver carp are released per acre, and 200 to 300 large-sized silver carp fingerlings can be raised.

Farming technology

Snakehead fish is a precious freshwater fish, known as the "treasure among fishes". It is a high-end health product with comprehensive nutrition and delicious meat. It has always been regarded as a tonic treasure for people recovering from illness and the old and young with weak constitutions. At present, the breeding of snakehead fish has significant benefits and has become one of the hottest aquaculture products.

1. Pond conditions

The pond should be selected with good lighting, ventilation, convenient water inlet and outlet, neutral or weak alkaline pH value, transparency of about 30 cm, water depth of 1.5 to 2 meters, escape prevention nets must be installed at the inlet and outlet, the bottom of the pond should be muddy, and the area should be 2 to 4 acres.

2. Fish species selection

Snakehead fish farming should be carried out with large-sized high-quality fish, with a size of about 10-15 cm, and 2,000 to 2,500 fish per mu, and 200 to 300 large-sized silver carp can be raised together.

3. Baiting Technology

1. Fresh bait: Snakehead carp is a carnivorous fish, and currently small fish are still the main feed, both freshwater and seawater small fish can be used. In the early stage of breeding, large wild fish are chopped and fed, and the daily feeding amount is generally about 5% of the total weight of the fish.

2. Artificial compound feed: Snakehead carp can also be fed with artificial compound feed, the formula of which is: 70% minced fish and shrimp paste, 20% soybean powder, 5% yeast powder, and the rest is multivitamin mineral salts, growth promoters and antibiotics. Feeding should be done at a fixed time, location, quality and quantity. Feed twice a day, once in the morning and once in the afternoon. When the feeding is vigorous, feed again in the evening.

IV. Daily Management

1. Patrol the pond: Patrol the pond every morning and evening, carefully observe the feeding and activity of snakehead fish, pay attention to changes in water quality, and deal with problems in a timely manner.

2. Change water: Once you find that there are too many leftover baits or the water quality is aging, you can inject new water and drain the old water to keep the pond water fresh and promote the normal growth of black carp.

5. Disease prevention and control

1. The pond should be cleaned and disinfected 10 to 15 days before the fish are put into the pond. When the pond is cleaned and disinfected by dry method, 60 to 75 kg of quicklime is generally used per mu; when the pond is cleaned and disinfected with water, 120 to 150 kg of quicklime is generally used per mu at a water depth of 1 meter.

2. Disinfection of fish: If you buy fish at the market, you must disinfect them before putting them into the pond. You can soak the fish in 2.5% to 3% salt water for 15 to 20 minutes.

3. Disinfect the dining table regularly by spraying it with bleach solution.

4. Although black carp has strong disease resistance, it is also prone to diseases after high-density breeding, mainly hemorrhagic disease, skin rot, scabies, etc. The treatment is carried out by combining oral and external application. 100 grams of chlorine dioxide per acre is sprayed on the entire pond every half month, and enrofloxacin is taken orally.

Snakehead carp farming should use large-sized, high-quality fish species, with a size of about 10-15 cm, with 2,000 to 2,500 fish released per acre, and 200 to 300 large-sized silver carp species can be raised in conjunction.

There are many advantages to breeding snakehead carp: snakehead carp has strong adaptability to the environment and low requirements for pond water quality, so it can be cultured at a high density, with high yield and high benefits; snakehead carp grows fast, and the fry bred in early spring can be grown into commercial fish in the same year; snakehead carp has few diseases and a high survival rate; and adult fish are easy to transport, making them convenient for long-distance sales.

There are two methods to hatch fish eggs: one is to artificially simulate the natural environment, inject oxytocin into the snakehead fish, and then put the male and female fish into the pond in a 1:1 ratio to allow them to lay eggs, fertilize, and hatch naturally; the other is artificial cage hatching.

There are two ways to raise adult snakehead fish: intensive farming and mixed pond farming. The program will introduce these in detail. In addition, the film will also introduce the reproduction of snakehead fish, the care and feeding methods of fry.

3,000 fish (3-5 per pound) are placed in one acre of land! The bait coefficient is basically 3-4 pounds per pound. The current market price is about 8.5 per pound and about 11 per pound! The profit depends on how much the bait is per pound.
